Distribution of the Segmental Nerves by which they are supplied, shown in a
Thoracic Segment.
NOTE.
A brief explanation of this diagram seems needful, in the interest of students who have not made a special study of comparative
anatomy. The muscles are grouped, first of all, into dorsal and ventral, the former being supplied by the posterior and the latter by the
anterior primary divisions, respectively, of the spinal nerves. The dorsal muscles form the great mass lying chiefly in the hollow between
the spinous processes and the angles of the ribs. They are classed in two group.s — superficial and deep. These need not be further
considered. The ventral muscles are shown to be arranged in three layers. In the abdominal region these are represented by three
actual muscles, to name them from within outwards : the transversalis, the internal oblique, and the external oblique. Continuous with the
deepest of these, the transversalis, for the purposes of this classification, are the triangularis sterni, the subcostals, the sternal and costal
portions of the diaphragm and part of the levator ani— these form the siihcostal layer. Continuous with the internal oblique are the intcr-
costals, the posterior serrati, the scalene muscles, and the quadratus lumborum — these form the intercostal layer. Continuous with the
e.vternal oblique are all the muscles connecting the scapula with the trunk, viz.: the trapezius, levator anguli scapulae, serratus magnus,
and rhomboidei muscles, also the iatissimus dorsi, the pectorals, the sternocleidomastoid, and the superficial perineal muscles— these
constitute what may he called the appendic»Iar\a.yi^T. There is finally a more superficial layer still (not shown in the figure), superficial
indeed to the deep fascia, corresponding to the panniculosus carnosus of lower mammals, but represented in man only by the platysma
myoides, the occipitofrontalis, and the muscles of the ear and face. — Tr.

divided, as shown in the ftjirure, by the middle or long head of the triceps into an outer, quadrilateral, and an inner, triangular, compart-
ment, called respectively hy Toldt the internal and the external axillary space. These names are not in use in England, but are suitable,
and may well be adopted. Through the external axillary space the posterior circumflex nerve and vessels pass backwards; and through
the mternal axillary space the dorsal branch of the subscapular artery passes round the margin of the scapula into the infraspinous
fossa. — Tr.

' Concerning these bursse Quain writes (" Elements of Anatomy." loth ed., vol. ii., Part II., p. 221): " In
many cases there is a small bursa above the olecranon, either between the tendon of the triceps and the
posterior ligament, or more frequently in the deep part of the tendon itself. A bursa behind the internal
condyle, beneath the inner edge of the triceps and the ulnar nerve, is of rare occurrence." — Tr.
- The epitroclileo-ancoiieus is a small muscle often found, which arises from the posterior surface of the interna!
condyle of the humerus, and is inserted into the olecranon. It is superficial to the ulnar nerve. When
absent, it is represented by a band of transverse fibres in the deep fascia of the arm. — Tr.

Ill order to display the intratendinous and the subtendinous burSEC of the olecranon, tno longitudinal
incisions have been made in the distal extremity of the triceps e.xtensor cubiti muscle, and the
posterior margins of the incisions have been retracted witli hooks. In the region of the forearm
the deep fascia has been left intact.

= The author adheres to the cld nomenclature of the short muscles of the thumb, but that introduced by Cunningham is now generally
adopted by English anatomists. Following this writer, the former adductor pollicis is called the adductor pollicis trans7'Crsrts, and what
used to be called the deep head of the jflcxor brevis pollicis muscle is divided into two parts. The larger part, known as the Oiiductor
oblitfiitis pollicis, the largest of the thumb muscles, consists of several slips arising from the upper ends of the second and third metacarpal
bones, the os magnum, the anterior carpal Hsaments, and the sheath of the tiexor carpi radialis muscle ; the muscle is inserted, in common
with the adductor transversiis and the deep head of the flexor brevis, into the inner side of the base of the lirst phalanx of the thumb.
What is now termed th-j decf> head of i^ttjlcxor brevis pollicis is a very small slip, deeply placed between the adductor obliqiius pollicis
and the outer head of the abductor indicis. It arises from the ulnar side of the upper part of the first metacarpal bone, and is inserted as
already described. — Tr. See also Figs. 573, 585, and 586.

I have given the preference to the old names, as more distinctive and therefore more suitable, of the three extensor muscles of the
thumb, e.rtcnsorossis tnvtacarfii pollicis, extensor prhyii intemodii pollicis^ and extensor secundi interyiodii pollicis. Quani (•' Anatomy,"
loth ed.) has, however, adopted the Continental nomenclature in the case of the two latter muscles, which he terms respectively extensor
brevis pollicis and extensor longus pollicis, whilst yet other names have been adopted by Macali^ter, who terms the extensor of the first
\>\\3\m\x, extensor pollicis minor, :ind the extensor of the second phalanx extensor pollicis major. The names used in the text are, however,
more faniiliar to students, both in England and America, and there seems no good reason for any change.
While speaking of these muscles, it may be mentioned that their tendons, viz., those of the extensor ossis metacarpi pollicis and extensor
primi intemodii pollicis on the radial side, and that of the extensor secundi intemodii pollicis on the ulnar side, bound the deep hollow to be
seen on the outer (radial) side of the wrist and behind the metacarpal bone of the thumb, when this member is fully extended. This hollow is
known as the tabatii're anatomique, or anatomical sntiff-lox (called by Toldt /oz'cola radialis, see Fig. 575). Beneath the tendons of
the extensors of the thumb, and across the intervening hollow, the radial artery pa-sses from the front to the back of the wrist, its direction
being indicated by a line from the front of the styloid process of the radius to the proximal end of the first interosseous space ; and the
arterj- is ci^ossed by the superficial radial vein, which usually forms a distinct prominence in the hollow between the tendcns. — Tr.
3 liy English anatomists the supinator and extensor muscles are, like those of the front of the forearm, divided simply into two layers : a
superficial, containing seven muscles, viz., the supinator radii longus, extensor carpi radialis longior, extensor carpi radialis brevior, extensor
comnmnis digiloriiin, extensor miuimi digiti, extensor carpi ulnaris, and anconeus muscles ; and a deep layer, containing five muscles, viz.,
the supinator radii brevis, extensor ossis metacarpi pollicis. extensor primi intemodii pollicis, extensor secundi intemodii pollicis, and
extensor indicis muscles. The author's classification of these muscles is to be found in the description at the foot of Figs. 574, 575, and
576.— Tk.

' PcsytmenHus. — The tendon uf insertion of the sartorius muscle sends cff fromits upper borderanaponeuroticcxpansion to join that
of the comtnon extensor over the front of the capsule of tlic I<nee-joint, and from its lower border another to the deep fascia of llie lej; ;
immediately below and behind this latter is a similar aponeurotic expansion from the ter.don of insertion f>f the gracilis mu^cle to the deep
fascia of the lep. From the resemblance of the aponeurotic expansions of the sartorius tendon to the footof a Roose, it is called by the
author /fj ttmcrinus, but it is to Ik: noted that this name is Kivcn by Knglish anatomists to an entirely different structure— to wit, the
plexus formed in the std>stance of the parotid t;land and on the side of the face by the fieely communicating twigs of the letnporofacial
and cervicofacial branches of the facial nerve, known also as the " parotid plexus" (see l''ig. 1314, p. 871, sect. vi. of this work).— Th.

synovial sheath, the fibrous strand which binds them down, passing from the point of the outer malleolus to the outer side of thecalcaneum,
being called by the author reihiacttltiin mm. peromeortim supcrhis (see Fig. 615, p. 366), and by English anatomists the external annular
ligament of the ank'.e. More distally, on the outer side of the calcaneum, each tendon has its own sheath, the two being separated by a
fibrous septum and by the trochlear process or peroneal spine of the calcaneum, when that process exists. The fibrous band which binds
the two tendons to the calcaneum has received no special name from English anatomists, but is called by the author retinaculum tnm.

2 By many English anatomists the extensor brevis hallucis muscle is regarded, not .as an independent muscle, but merely as the inner-
most slip of the extensor breviis digitorum pedis muscle, and under these circumstances the extensor longus hallucis muscle is termed
extensor proprius hallucis. — Tr.
3 The name opponens minimi digiti {pedis) is sometimes given to that portion of the Jlexor brez'is minimi digiti pedis muscle which
is inserted into the fifth metatarsal bone (the Imlk of the muscle being inserted into the base and external border of the proximal phalanx.
Occasionally (3'^ per cent.) this portion of the muscle is entirely separate from the rest ; while somewhat more frequently (10 per cent.) the
insertion of the flexor brevis minimi digiti into the metatarsal bone is entirely wanting. — Tk.

Of the deep fascia of the leg. the lower portion of the superficial layer, which binds down the tendo Achillis, and the deep
layer, which passes from side to side between the superficial and the deep posterior muscles of liie leg, have been
retained. The plantaris muscle and its tendon are partially visible.
J The author divides the posterior muscles of the leg into three groups or lavers, the 6rst. most superficial, consisting of the gastroc-
nemius muscle ; the second consisting of the plantaris and soleus muscles ; and the third, deepest, consisting of the popliteus, flexor longus
hatlncis, flexor longus digitorum pedis (or flexor perforans), and tibialis pt>sticus muscles. This arrancement appears a ver>' artificial one,
and I have therefore adhered to the arrangement usually adopted by English anatomists, according to which the muscles are grouped in
two layers only : a superficial, consisting of the gastrocnemius, soleus, and plantaris muscles ; and a deep, consisting of the muscles already
enumerated as making up the author's third layer. — Tr.

3 Like the author, English anatomists group the muscles of the sole in four laj'ers, but the two classifications are not i^ntirely identical.
That of the author is given in the description at the foot of Figs. 625 to 628. ^ According to English anatomists, thejirst or superficial layer
consists of the flexor brevis digitorum (or flexor perforatus), abductor hallucis and abductor minimidigiti muscles ; the .Jtri>7/</ layer consists
of the tendons of the flexor longus digitorum (or flexor perforans) and flexor longus hallucis muscles, together with the flexor accessorius
and lumbricales muscles; the ////></ layer consists of the flexor brevis hallucis, adductor obliquus hallucis, adductor transversus hallucis,
and flexor brevis minimi digiti muscles ; and the foitrth layer consists of the dorsal and plantar interosseous muscles, together with the
tendons of the tibialis posticus and peroneus longus muscles. — Tr.

suspensory ligament, "The former, called by the author ligamentiDu funk forme penis, when artificially separated from the fascia of the
abdomen and the dorsum of the penis (of which it forms a part), is a flattened piece of connective tissue with edges directed laterally and
surfaces directed forwards and backwards, respectively. The latter, called by the author iigamenium sitspensorium penis, when dissected
out, has an anterior free edge, a postero-superior edge attached to the front of the pubic symphysis, and a postero-inferior edge attached
to the dorsum of the penis, whilst its surfaces look to right and to left (see Fig. 632). The false suspensory ligament contains many yellow
elastic fibres ; the true corfrists of while fibres only. — Tk.

' Anomalous OMuraior Artery. — The normal origin of the obturator artery is from the internal iliac artery, and it sendsan anastomotic
branch to the deep epigastric artery ; but quite frequently this anastomotic branch becomes the main trunk, so that the obturator artery-
arises, as here, from the external iliac in common with the deep epigastric. When the anomalous obturator artery takes the course shown
in the figure, directly downwards across the internal iliac vein to reach the obturator canal, the anomaly is of little practical importance ;
but in some cases (once in fifty-eight bodies, and more often in males than females) the anomalous obturator artery courses first inwards,
and then arches backwards on the inner side of the femoral ring, so that it is in danger of being cut when dividing the stricture in cases of
strangulated femoral hernia. — Tk.

» Fascia Iliopeclinea. — The author distinguishes by this name that portion of the iliac fascia (of English anatnniists) which, covering
the iliopsoas muscle as it passes beneath Poupart's ligament, forms the septum between the iliac cotnf'aytmeni and the z'ascular compart-
ment of the space beneath that ligament, and passing inwards behind the femoral vessels to form the posterior layerof the femoral or crural
sheath becomes continuous with the pul'ic portion of the fascia lata of the thigh, ox pectineal fascia (see description at foot of Fig. 508),
]). 349. From the fact that this portion serves to connect the iliac with the pectineal fascia arises the name " iliopectineal fa.scia."— Tk.
